I'm thinking about adding a large side quest in this that would be akin to the Origin of the Mages Guild but better. No new resources, just existing ones so no huge additional downloads. It would feature a council chamber except the council would actually meet and if you're Arch Mage you can participate. I think it would be bigger and better over all without all the issues of the other one. It would feature Valas, Viconia's brother as a Council member and your main contact.
I think it would be good to have two or even more major quests in this to keep you very busy.
